Description

Itarget MP

Usage

Itarget(
  x,
  Data,
  reps = 1,
  w = 0,
  lambda = 0.2,
  delta = 1,
  xx = 1,
  index_target_window = 10,
  index_current_window = 5,
  catch_target_window = 5
)

Itarget_base(x, Data, reps = 1)

Itarget_w0.8(x, Data, reps = 1)

Itarget_x0.2(x, Data, reps = 1)

Itarget_x0.8(x, Data, reps = 1)

Itarget_d1.2(x, Data, reps = 1)

Itarget_d0.8(x, Data, reps = 1)

Arguments

x

A position in the data object. As per MSEtool.

Data

A data object. As per MSEtool.

reps

The number of stochastic samples of the MP recommendation(s). As per MSEtool.

w

A smoothing parameter that defines the "steepness" of the adjustment slope.

lambda

Fraction of the average index over the 10 years prior to the projection period below which future TACs are reduced quadratically.

delta

⁠I_{target}⁠ is ⁠(1 + \delta) I_{ave}⁠; the target index value.

xx

Catch target defined as ⁠(1 - xx)C_{ave}⁠, where xx is the proportional difference between the future catch and the average historical catch over the last 5 years of the historical period.

index_target_window

Index target window in years.

index_current_window

Index current window in years. Years over which the average index is calculated.

catch_target_window

Catch target window in years.
